IMPROVEMENT IN MEANS FOR FEEDING WOOL AND OTHER FIBROUS MATERIAL TO PICKINQVCARDING,

AND OTHER SIMILAR MACHINESa Sprcilcat'iou forming part of Letters Patenty No. 47.9765. dated May 3U, 1R65.

T0 (all whom t may conce/371,:

Be it known vthat I, STEPHEN It. PARK- HURST, of Bloomeld, in the county of Essex and State of New Jersey, have invented, made, and applied to use a certain new and useful Improvement in Means for Feeding Tool and other Fibrous Substancesto Picking, Carding, and Similar Machines; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is a section crosswise of the toothed cylinders employed by me, and Fig. 2 is a dctached elevation of my vibrating comb and t-he cylinders withwhich it operates.

Similar marks of reference denote parts.

The nature of my said invention consists in a vibrating comb applied to and combined with a toothed cylinder, and operating in such a manner that the comb, when moving in one direction, clears the bers, burrs, Src., out of the same the teeth of the feeding-cylinder, and the comb itself, when moving inthe other direction, is cleaned against the teeth of the cylinder, by which movements the wool or other ber is loosened and `pulled apart gradually. I combine with said feedingcylinder and vibrating comb` a toothed cylinder that conveys thcwool or other ber from the feeding-cylinder, and from the comb tothe burring, carding, or picking mechanism with which my improvement maybe applied 0r combined; and I employ a shell vibrating withthecomb to catch any loose pieces of wool or other ber and convey them back to the burring-cylinder.

In the drawings, c represents part of a feeding-belt to supply the wool or other ber to the machine. It might, however, be supplied by a hopper or any other suitable device.

b is a feed-cylinder, with inclined teeth, ro-

` Jfated in the direction shown, so that the teeth go backward, and c is a feed-roller above, also formed with inclined teeth which move backward. d is a third cylinder or roller, which becomes a burring cylinder, as hereinafter shown. These three cylinders or rollers may have the teeth formed in any desired manner. I, however, prefer and use steel rings with -of c are drawn out, and the undercut teeth, as shown on cylinders b and d.

The cylinders b and c act as iced-rollers, alid only travel fast enough to convey in the proper amount of ber. The cylinder d travels much faster; hence it combs out the ber against the points of the teeth on b as they travel backward. rIhe ber is a so held back by the teeth of the feed-roller c, and hence is opened and combed by the quicker-moving cylinder d, and at the same time any bers adhering to the teeth 'cylinder c kept clean by the action of the cylinder d;

e is a comb, the teeth of which point in the same direction as the teeth on the cylinder b. This comb is to be vibrated close to the surface of thev cylinder b, and move up toward and then draw back from the cylinder d. This comb e is to be vibrated by any suitable device. I, however, prefer and use the following means: ff are circular' heads placed oneat 1each end of the cylinder b, and freeM to move loosely upon its axis, said heads being of somewhat larger diameter than the cylinder, and connected bybars g g, extending from end to end of b. One of these bars g terminates with projecting pins l l, taking the straps It h of the eccentrics z' z', that are afxed to the shaft of the burringcylinder d. These eccentrics give tothe heads f and bars g a vibrating or oscillating movement in the arc of a circle whose center is the axis of b, and to one of these bars g the aforesaid comb e is affixed, and also a shell, k, that is curved and comes up nearly to `the surfaceof the burring-cylinder d, and is about concentric therewith, when the comb is fully raised by the eccentrics. I provi de a stripper, Z, rotated in the direction indicated, that knocks oft' burrs from the wool or other ber that is carried by the teeth of the cylinder d. Said burrs fall down upon the oor bene: th the machaine; or they may pass into any suitable receptacle. Theburring-cylindercl, traveling much faster than the feeding-cylinder b,

communicates to the comb e, through the eccentrics, a vibrating movement that is faster than the travel of the surface of b,- hen ce when the comb moves back or in the same direction as the surface of b, the teeth of b will take the" wool or other ber and hold the same as the comb draws out from the ber, and then the comb,as it moves the other way, (or toward eZ.) cleans the teeth of b of any bers or burrs that may remain and not have been taken away by the cylinder d, and when the comb e comes up toward the cylinder cZ, said cylinder takes the wool from said comb, drawing it away against the said comb-teeth, and opening, loosening, and separating the locks of wool, so that the burrs will fall out freely, and some of the burrs pass down between the comb and cylinder b, while others are removed by the stripper Z.

The object of the shell k is to catch and return to the cylinder Z any locks of wool or other ber that might fall away in being opened by the action ofthe comb and cylinders b and d. This 'shell 7c keeps any loose wool up to the cylinder (Z, so that the teeth will rmly hold said ber, and when the shell is drawn away from the cylinder cZ it will catch any locks of wool that the stripper Z may throw down and carry them again up to the cylinder d. The second burring-cylinder, m, travels faster tha-n d, and takes the wool up in asheet or bat, exposing thel other side to the action of the stripper a, the same as in my patent of .I une 17, 1862.

It has been usual heretofore to employ a toothed cylinder to transfer the ber from a burring-cylinder to the main cardingcylinder. This is termed the .licker in.77 To avoidthe use of this licker in, and thereby obtain room for a larger number of pairs of workers and strippers in the carding-machine, I place the rst stripper, p, so as to run contiguous to the burring-cylinder fm, and transfer the wool or otherber to the main carding-cylinder o. q is the rst worker, taking the locks of ber from o and carrying them to the stripper p, by which they are brought back to the burring-cylinder and mixed with the wool passing from that cylinder to the stripper p, thus mixing up the wool muchv more eifectually than heretofore. The other pairs of Workers, r and s, are provided, as usual, and actuated in any convenient manner.

The frame-work for sustaining my cylinders, Sto., is to be of any usual or desired character, and pulley and belts Vor gearing of any usual kind are to be employed for rotating the cylinders, rollers, &c., at the proper speed.

I have only shown a portion of the main carding-cylinder o, and the dotted red lines represent a frame that may be employed. It will be evident that any desired character of teeth may be employed on the cylinders b, d,

and m, according to the work to be performed, v

and where the machine is to be employed for carding the ber a second time after the burrs have been removed, the cylinder m and strippers Z a might be dispensed with, and the cylinder cZ placed contiguous to the main cardingcylinder o, or to any other cylinder on a carding-machine, and I do not limit the use of my invention to the burring of wool, but intend to use the whole or any portion thereof for burring, carding, picking, or cleaning any character of ber, and apply the same to any character of machine where it can be employed.

Vhat I claim, and desire to secure by Letters Patent, is

1. rIhe combination of a vibrating comb with a toothed cylinder for removing wool or other ber and foreign substances from the teeth of said cylinder, and also cleaning the teeth of said comb, substantially as specied.

2. The feed-rollers b and c, in combination with the vibrating comb, substantially as specied.

3. The combination of a feeding-cylinder, b, vibrating-comb c, and burring-cylinder d. for the purposes and substantially as specied.

4. rIhe combination of a shell with the vibrating comb and toothed cylinder (Z, for the purposes and substantially as specied.

5. The heads ff, connecting-barsl g, and eccentrics, in combination with the vibrating comb and cylinders b and cZ, as set forth.

6. The combination of the burring-cylinders d m and strippers Z and n with the feed-cylinder b and vibrating comb e, substantially as specied.

7 rlhe combination of the barring-cylinder m, the stripper p, the worker q, and the cai-dingcylinder o, substantially as specied, whereby the stripper p transfers the ber from the burring-cylinder to the cardingcylinder, as set forth.

In witness whereof I have hereunto set my signature this 6th day of January, 1865.
